- ments in Ledgers, of which the following is a specification, reference being had therein to t e accompanying drawings.

The invention relates particularly to -a loose-leaf ledger, and has-special reference to i a novel type of back therefor, consisting of complementary sections adapted to beseparated to permit of the insertion or withdrawal of leaves and closed been lnserted.

.The inventlon consists 1n the novel construction of the back, in the operating means for adjusting the-back-sections, and in other. details of construction, as more fully herein' after set forth. i g v In the drawings, Figure 1v is a sectional perspective view of a ledger, showing-our improved back therefor.

tive view of a portion' of one of the side sections. Fig. 3 is a detached perspective view of the back proper. Fig. 4 is a transverse section through the ledger-back, and Fig. '5

cross-slot G is a section taken on line w m, Fig. 1.

In the drawings thus briefly described the reference-letter A designates the ledger-back, comprising in this instance a back proper, B, in the form of a supporting-plate,- upon whichare mounted for transverse movement two complementary inclosingside sections 0 and D.

E andF represent the ledger-covers;which are hinged to the upper edges of the side sections in any suitable. manner.

The back proper or plate," as itwill be hereinafter termed,'is provided at its center with a longitudinal bearing G, having a i at intermediate points with I separated bearings H and adjoining bearingfaces I below the bearings H and at its extreme ends with bearing J,'for1ning in connection with the bearings'I supports for the sides.

' The ends of'the plate are also flanged, as'indicated at K, to engage over the ends ;of 'the side'sections, andthe'bearing J at one of the plate ends is grooved, as at a, to permit of.

the insertion through the back of the operating member for the sides. 1

Mounted upon each pair of bearings His an adjusting-plate L, slotted, as atb b, to receive securing-screws c c, which serve to hold the plates upon the back plate, and provided adjoining ends of the platesdescribed are threaded bearings e, engaged by right and left hand threads, respectively, upon a screw -membe rM, which forms the operating device for the plates and which upon actuation away from each other, the screw member, as shown, engaging the having a shoulder at, engaging the cross-slot G to form'the swivel. eration, the screw projects beyond one side .of the ledger, as indicated in Fig. 1, and is preferably squared-at its end, so as to be operated by a suitable key, as O.

The side sections C and D are provided with projections in the form of pins P, which engage the guide-slots, as indicated, and carry on their, vertical ries of post-sections R, the posts being preferably of telescopic type, having the usual engagement indicated in Fig. 4. The meeting edges of the side sections are also recessed, as at g, to receive the bearings'H and permit the sides to be moved into close one another'when the ledger is closed.

In use when it is desired to remove a leaf of the ledger or insertanother the operator by actuating the screws causes the adjusting-plates for the sides. to either move apart or toward each other, according as is to be opened or closed. The plates acting uponthe pins in the guide-slots compel the desired transverse movement of the side sections and also. look the. sides in anydesired position relative to the back plate.

What we claim is 1. In a loose-leaf ledger, the combination with a ledger-back comprising a back proper and transversely-movable side sections thereon, of adjusting-plates for said side sections each having two pairs of guide-slots, one of said pairs engaging projections on said back proper, the other on said side sections and means of adjusting said plates, for the-purpose described.

2. In a loose-leaf ledger, the combination witha ledger-back comprising a back proper and transversely-movable side sections, of

compels "movement of the plates toward or central bearing G and with a'pair of guide-slots, as d d. Upon the To permit of its opportions Q each a seproximity with the ledger 4 pair engaging projections vertical and horizontal end bearings and horizontal intermediate bearings on said back proper engaging the side sections, for the purpose described;

3. In a loose-leaf ledger, the combination with a ledger-back comprising a back proper and transversely-movable sides, of means mounted on said back proper for adjusting said side sections, bearings on said back proper engaging said side sections, and legs on said back proper engaging notches in said side sections, for the purpose described.

4. In a loose-leaf ledger, the combination with the ledger-back comprising a back plate and two complementary inclosing side sections mounted upon the plate for sliding
